I've read many times of folks who block off their roof vents for maximum heat retention during cold weather.
I question always comes to mind: How do you then maintain some ventilation inside the RV while these are blocked off? We always keep the vents open just a little (we have Maxxaire covers over them) for ventilation .... even in cold weather. This also helps control excessive moisture build-up from cooking and breathing when spending long periods inside.
We've never had a problem with interior condensation because the electric or propane heater dries out the air.
